j y To all whom 'itmayconfiere."k

Beit known' that I, JAMES J. DAVIS, a citi- Zen of the United' States,residing at Columbus., .in the county of `Franklin and State of Ohio,have invented certain new and useful Improvements in Meansfoi-vl7ar-miiig Show- I lVindows, f cation.y

of which the following is a specifif My invention relates to theimprovement of means for warmingshow windows and the objects ofr myinvention are to provide improved means for imparting to theinnersurfaces of show windows, heat suflicient to prevent the formationthereon of frost or visible moisture ,to so construct my improvedheating appliance as to provide an equal distribution ofthe heated airover the' window surfaces; to prevent the mixture of burned gas andheated air and to produce other improvements,"the details of which willbe more fully pointed out hereinafter.

f These objects I accomplish in the manner illustrated in theaccompanying drawing, in

which:` t

Figure 1 is la transverse section of a store-A .room` floor `showing theinner surfaces of store kkwindows withmy improved window warmingmechanism in place, Fig. 2 is a secvshow windows or glass window plates,which tional -view on line `ach-.t of Fig. 1, Fig. 3 is a 'plan v iew ofone of the heat distributing pipe retaining plates, and,fFig. v4r is asectional viewon line 2 2; of Fig. 3.

Similar numerals refer to similar parts throughout'the several views.

`l represents the iioor of a store-room, 2 the forthe purpose ofillustration I have shown y on opposite sides of a door 3, and 4 repre-.f l sents the window display iloors or platforms which ordinarilyprojectinwardly from the bases of ythe window frames which are indicated at 2a.

an upright heater casing `rt which has the general form of a truncatedcone and the lower end of which is open. zontally yinto, the casing r6,is a gas supply pipe 7 which carries centrally in said casing a'perforated burner ring 8.'` Extending throug this ring and supportedtherein, is the lower end of a central vertical air tube 9, the upperend of which in the upper portion of the casing supports the upper endof a second or Extending hori-l intermediate substantially cone-shapedcasing 10, with an opening in the upper end of which the tube 9communicates. Leading horizontally outward from the upper portion of thecasing lO'is an outlet pipe 11 provided with a suitable damper 12.

From the upper end oil the conical casing 6 lead upwardly and outwardlythe desired number of heat conducting pipes 13, each of the latter beingprovided with a"` suitable damper 13a. Each of the pipes 13 leads to thecentral portion of a horizontal head or pipe section 14 which is locatedbeneath the floor 1 and beneath the display platform of a window. Fromeach of these pipes 14 lead upward through the iloor 1 and thencethrough openings in the display platform 4, a plurality ofcomparativelyl small pipes l5. The openings in the windowplatforrnthrough which the heat distributing pipes 15 lead, are arranged in alongitudinal ro'w at intervals one from the other adjacent to the innerside of the lower window frame bar 2a and that portion of each of thedistributing pipes 15 which projects through the platform, iits withinthe central opening of a suitable me* tallic plate or disk 16 which isscrewed or otherwise secured to the upper surface of the platform 4.

In operation, it will be understood that when the gas is lighted at theopenings of the burner 8, the heat generated thereby will operate toheat the tube 8 and the outer and inner casings 6 and 10, with theresult that the air which will be drawn upward between said outer andinner casings will become heated and will pass outward through the pipes13' that any tendency of moisture to accumulate' on the window glassthrough condensation occasioned by the warmer air of the interior o'l`the store coming into contact with the colder glass, will be obviated.In this manner it will be understood that show windows may be kept clearof obstruction and in a desirable transparent condition.

Owing to the provision in the heating a1pparatus of the internal casing10 and t e outlet 11, it will be understood that the lIO burned gas orproducts of combustion which may arise from the burner, may pass out-Ward Without becoming mingled With the heated air which passes throughthe external casing and through the tube 9. Although I have shown a gasburner in connection with the heating device, it is obvious that othermeans of heat generation may be employed.

WV hat I claim, is:

l. In a show Window Warming means, the combination of a heat generatorand casing supported beneath a store-room floor, heat pipes leadingupward therefrom, and horizontal pipe sections connected with thedischarge end of said heat pipes, of a plurality of Vsmaller heatdistributing pipes leading from said horizontal pipe sections to pointson the inner side of and adjacent .to the bases of display Windows.

2. In a show Window Warming means, the combination With a heatingappliance supported beneath the floor of a store-room comprisingseparated external and internal casings, said internal casing having anoutlet in its upper portion, and heat generating means in its lowerportion, heat pipes leading upward from said outer casing, horizontalpipe sections connected With the upperends of said heat pipes, and aplurality oi' smaller heat distributing pipes connected with each ofsaid horizontal ipe sections, said heat distributing pipes Aaving theiroutlets adjacent to they inner sidesfof the bases of the store windows.

3. In a show Window Warming means, the combination with a heatingappliance supported beneath the iloor of a store room, of an enlargedhorizontally disposed heat pipe, a heat conducting pipe leading fromsaid heating appliance to Vsaid heat pi e, said heat pipe being alsolocated beneath t e floor, and i Va plurality of smaller pipes risingfrom said heat pipe and passing through the iioor of a show Window.

4. In a show Windowv Warming means, the combination with a heatingappliance supported beneath the iloor of a store room, of an enlargedhorizontally disposed heat pipe, a heat conducting pipe leading fromsaid heating appliance to said heat pipe, said heat pipe being alsolocated beneath the iioor, a plurality of smaller pipes rising fromsaidheat pipe and passing through the floor of a show Window,`plates intoWhich the upper ends of said pipes project, said pipes being located ontop oi the show Window iioor, and means for securing said plates to saidiioor.

5. In a device of the character described, the combination With a shoWWindow, .of a heating appliance supported beneath the Hoor of a storeroom in Which said show Window is located, said heating pipes comprisingse arated external and internal frustoconicacasings closed at theirupper ends and open at their lower ends, a tube )assing from the innerof said casings, an out et pipe leading from the upper portion oi' theinner olA said casings, a burner located in the inner oi' said casingsand supporting said tube, a heat conducting pipe leading from the upperportion of the outer casing, an enlarged heat pipe to which said heatconducting pipe is connected, a damper in said heat conducting pipe, anda plurality of smaller pipes extending from the enlarged heat pipe toand through the floor of the show Window.

In testimony whereof I ax my signature in presence of tWo Witnesses.

JAMES J. DAVIS.
